C-More EA9 HMI Object List Indicators

The C-More HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Pushbuttons, switches, meters, and graphs are just a few of the objects that are available to you.

C-More Indicators Objects

Indicator objects refer to single bits or words in the PLC that can signal an object on the C-More HMI screen. The control of these tags are done by the PLC program. Our C-More EA9 will just react to this information.

C-More Indicator Light

The indicator light object is an electronic version of a typical pushbutton indicator light normally found on control panels. This indicator light object can be assigned a tag name and used to indicate the status of bits in the PLC.
Select Screen 5 from the navigation window. We will now add an Indicator Light under the Object list window. Left click (hold) and drag the Sample-2 under the Parts List for the Indicator Light onto the screen.

HMI Programming Software

PLC Program Additions – C-More Indicators

Using the program we previously developed, we will add additional rungs to control the indicator objects that we have just created.
PLC Ladder Logic Sample Program
When input X8 turns on MI30 (Modbus 10030) will turn on.
PLC Ladder Logic Sample Program
X9 will indicate that the Valve Indicator Open is active. X10 will indicate that the Valve Indicator Close is active. If both or neither of these inputs are on/off then the valve will indicate it is in transit.
PLC Ladder Logic Sample Program
Here is our numeric display. We have scaled the input in the C-More HMI so that when the input goes from 0 to 4095, the display will show 0 to 1000.
PLC Ladder Logic Sample Program
WX5 will indicate what message will be displayed on our C-More HMI. This is using the Multi-State Text Indicator. In our case, we are using the message number in the word as opposed to the bit in the word.

Download the PLC and C-More program here.

Watch the video below to see the Object Indicators in action on our C-More EA9 HMI Panel. This will also demonstrate the PLC ladder code for functionality.
